litellm: add OpenAI→Meridian shim role (venv + systemd, port 4000)

LiteLLM sits in front of Meridian for clients that can't talk Anthropic's
/v1/messages format (Pulse OpenAI provider, paperless-ai, etc.). Routes
OpenAI-shaped requests to localhost:3456 (Meridian) which forwards to the
Max sub.

- New roles/litellm/ — Python venv, pip install litellm[proxy], systemd
- vars/main.yml — model map (haiku/sonnet/opus) + LITELLM_MASTER_KEY env lookup
- site.yml — adds litellm role + sanity-check assert
- deploy.sh — pulls LITELLM_MASTER_KEY from Infisical (/meridian/) on the
  controller and exports it for the playbook
- New Infisical secret /meridian/vault_litellm_master_key

Smoke: Pulse → LiteLLM /v1/chat/completions → Meridian /v1/messages → Max sub
returns "pong" through both the LiteLLM master key auth and the Claude Code
SDK OAuth.
